Request: Windows Support

[richinseattle]

Hello, I discovered your crate as dependency of dynamorio-rs / drstd which are rust safe bindings over dynamorio-sys. DynamoRIO is a cross platform binary instrumentation platform for Windows and Linux for debugging and tracing software. I see some cfg variables in your toml referring to Windows but the use of iovec is causing build failures. Did I miss something or is Windows support still WIP? I would be a happy customer if it worked on Windows. Thanks!
